To all 7.0710712 2'2- nmg concern.

lie it known that l. GnononC. ihBBI'l fl citizen of the ll'nited States. residing in lainallowne. Delaware county. Pennsylvania, have invenl'ed certain Improvements in Reels for lliline-Lz co1no'lives, of whieh the following: is a SIWClillfiilllOll.

One object of my invention is to flil'ev'icle means for accumulating sufiicieni. air under pressure lo :lrive the cable drum of an electric loconieli e no that the slack he taken up at all ill and especially if the engine should slip or slide on the rails.

A further object of the invention lf-l to so construct the parts that the mechanism will take up but comparatively little room, yet will lie ell eclive for the purpose for which it is i tended.

In the accompanving (lrawings,-Figure l, is a plan view of an electric loconioiive, (to illustra'ie my invention parts of the nicchanisni have been omitted in order to avoid confusion); Fig. 2, is a SlLiQ view of an electric hicon'io'tive shown in .l, and l 3, a transverse sectional view on the line 323, Fig. 1; illustrating the cable llruin in eefilion.

A is the frame of an eleciric locomotive loving axles ll-ll' on which are n-ionntell li ll l irariion Wheels l).

i. ll are the motors by which the locomotive is driven. In the present instance there are live molors one 2110601 mounlerl on one i and llie other motor mounted on the ier axle.

l the cable drum having flanges l cable. drum, as shown in Fig. 3, 15 mounted on two spindles E and F. The spindle E is secured to hearings e on the fram A and the spindle F is arlaptell to hearings f also mounted on 'lhe frame A. The llllllll 11 in hollow, shown in Fin. 3, and mouolell Wiihiu the drain at one end. is

an air engine (l: The crank axle 5/ of this engine has a pinion g" which meshes with an internal gear ii on a easing H secured to the spindle F. The engine rotates with the H is a fixture, in the drum. While the can:

a around which passes a chain n over a Sprocket wheel I) from the axle B and a pipe 0' extends from the air compressor lo the spindle E, which is tubular for part of its length. In the pipe 0 a safety valve 6 which can h sci at any pressure desired. The naseage c in lhe spindle coinn'ninicales the interior of the drum, clearly slnwsn in l' The engine casing; couiniunicates W1 h the drum through the posaagze and the llllllllSblOll of air to the cvlincler of the engine is controlled liy a valve 51 operalerl in the present inslauce'lvv a pinion which meshes with the internal gear ii on the casing ll.

l 'hile l have shown a particular form of engine using two cylinders G5 and a particw lar form of valve. any suitable air engine may he used without departing from the essential features of the invention.

The operation of the mechanism is as follows: The locomotive receives ils supply of current through a trolley or third rail anrl each locomotive has a iii-urn on which is wound a cahle so hal -when a. locomotive enters a side room or gallery, for instance, in file .iinc, which is not supplied with a permanentsuriace rail or wire, the cable is attached. to the permanent Wire in the main gallery and the cable is naicl out as the loco motive p: as into the side room.

llhile these locomotives are provided with b alive and other appliances for contniilling lhe loconwtive, nevertheless, the wheels oftentimes slip and, consequently, the cal e will become slacl; or loo tin-it as heretofore the (lruni was driven directly from the axles. By my invention the locomoliiw drives the air compressor N and the emnpresserl air is forced into the hollow clruin D, which heeoines a. container for air under pressure and the air from this drum is supplied to the air engine G which rotates the drum in one (lireczion. to wind the cable upon ehe clrum. The drum is of such a capacity as to store euilicienl; air to retake it a certain length of time when 5 ie locomotive is not in motion.

irefer to utilize the engine as an air con "iressor when the cable is being paid out an; the safely valve/2 will control the ere CL 5 pressure developed either by the air compressor when the locomotive is traveling which said drum is rotatably mounted, said axles, and

' contained air a long distance, or when both the air comprcssor and the engine are pumping air into the drum.

1. In a mine locomotive, the combination of a frame, axles upon which said frame is mounted, means for driving one of said axles, an air compressor mounted on said frame and driven from said axle, a hollow rum, bearings carried by the frame in drum forming a combined cable reel and storage chamber for compressed air, a selfengine carried by said drum for driving the latter, a pipe or conduit connecting the air compressor with the interior of the drum, and means affording communication drum and the air engine carried thereby.

2. In a mine locomotive, the combination with a frame, axles upon which said frame is mounted, means for driving one of said an air compressor mounted on said frame and driven from said axle, of a hollow drum forming a combined cable reel and storage chamber for compressed air, an air engine mounted in one end of said drum and rotating therewith, gears driven thereby, spindles on which the drum is mounted, one of said spindles being hollow and opening into the drum for the passage of, air under pressure from the compressor; the ports of said engine being in direct communication with the interior of said drum, said engine acting as a pump during rotation of the reel as the cable is paid out and acting to drive the drum to coil the cable thereon, and fixed between the interior of the gearing carried by the frame of the structure for engagement by the gearing driven by the engine. I

3. The combination of a hollow drum forming a combined cable reel and storage chamber for compressed air, a spindle upon which one end of said drum is mounted for rotation, a spindle rotatable with the drum for the opposite end of the same, fixed supports for said spindles, and an air engine for driving said drum mounted in one end of the latter and in communication with the compressed air chamber' formed by said drum.

4. The combination of. a hollow drum forming a combined cable reel and storage chamber for compressed air, which one end of said drum is mounted, for rotation, a spindle rotatable with the drum for the opposite end of'the same, means for supplying said drum with air under pres sure, fixed supports for said spindles, an air engine for driving said drum mounted in one end of the latter and in communication with the compressed air chamber formed by said drum, a fixed frame disposed at the engine end of said drum, an internal gear carried by said frame, and a pinion driven by said engine and meshing with said gear.

In testimony whereof, I have igned my name to this specification, in the gresence of two subscribing witnesses.
